The meeting to discuss the loop holes of Congress party held at Sonia's residence 10 RCR in Janpath in New Delhi.
Top leadership of the party had pledged "deep introspection"
Mizoram is the only state where the Congress emerged winner. It was a loser in all the others including Delhi and Rajasthan where it was the ruling party.
The seriousness of the exercise could be gauged from the fact that senior ministers like A K Antony and Ghulam Nabi Azad skipped a meeting of the Union Cabinet to attend the consultations.
After the two-hour-long meeting, the leaders including party general secretaries declined to talk to reporters nor any information was available officially from the AICC.
There was speculation that the AICC in-charge of the states where Congress lost have offered to resign but there was no confirmation.
Asked about the speculation, one of the participants in the meeting declined to comment.
Soon after the results in Madhya Pradesh, Congress campaign committee chief for the assembly elections in the state Jyotiraditya Scindia had called for "major reconstruction" and introspection in the party.
"On all accounts we failed, failed and failed. There is a need to relook.... It is the collective leadership of the party in the state (responsible for the loss)," he had said.
Stunned by the drubbing in assembly polls, top leadership of the party had pledged "deep introspection" with a view to "transform" the party to rectify its mistakes ahead of the 2014 Lok Sabha elections.
"We have to look into the way we took or did not take our message to the people and also we have to look at the way our own party is equipped or not so equipped in running an election," Ms. Gandhi had on Sunday said.
At the AICC briefing, party spokesperson Meem Afzal was subjected to a host of questions as to who should be held responsible and whether Ms. Gandhi and Mr. Rahul should not take the blame for the dismal show.
To this, he replied that the Congress chief and vice-president had already accepted the party's defeat.
He attributed the Congress' rout in Madhya Pradesh to reasons including the inability of the party to take the message of unity of its faction-ridden unit before people and an ineffective campaign.
The result for four states in the assembly polls were announced on Sunday. While, results for Mizoram came on Monday.
